There is nothing to support that Apache has problematic buffer overflows.
Most of the problems over the past year or two have been related to poor
processing rather than overflows. We've had a couple overflows on Windows,
but that's about it.

Heck, there isn't anything that says that Subversion doesn't have buffer
overflows. New code. New problems.

And you know... for that matter, has anybody actually audited CVS? Hoo... I
have seen its network code. Ohmigod. I double-dare you to audit that.

One port for subversion is not a big deal. Your admins will still need the
sshd port, but you can reduce your logins to *JUST* the admins. The devs
don't need system accounts or access to the sshd port.

You're trading one port for another.

That would be interesting, and we'd certainly accept the code, but I don't
think it will buy you much (for your use case) relative to Subversion over
